I am wanting to upgrade the drivetrain on my bike but I have very little knowledge on the subject.
The bike in question is a lowly Mongoose mountain bike bought at a local sporting-goods store. It is a 21 speed. Part of the reason for the upgrade is that the new wheelset I recently bought requires the purchase of a cassette instead of a freewheel. The other reason is the cheap low quality parts used on the rest of the drivetrain.
My plan is to upgrade the...
... while doing this I plan on removing the front derailleur as I really never use it.
Here are my questions.
1) Am I correct in thinking that my new wheelset is set up for an 8 or 9 speed cassette instead of a 7 speed? Here is the wheelset I have http://pricepoint.com/detail/12001-3...-Lite-Rims.htm
2) Since I want to ditch the front derailleur I would think 9 speed would be better?
3) If I choose 9 speed is there a 9 speed specific crankset? (Specifically one with a single chain ring.)
Please add anything I may have overlooked and feel free to recommend budget priced parts.
Thanks for any and all help.
